Review on HD Backup Camera System Kit With Monitor - ZEROXCLUB 9, Loop Recording, IR Night Vision Waterproof Camera W/ Safe Parking Lines For Bus, Semi-Truck, Trailer & RV (BY902A) by Luis Despain

I have not mounted unit and drove at highway speeds yet but plugged in and tested functionality and seems to be very high quality. Looking forward to installing in the spring.UPDATE 1/2/19: Customer service has beyond outstanding. Also had a bad AC power plug and was replaced immediately with an upgraded plug.UPDATE 10/6/20: Installed on a 35 foot travel trailer and took off for a 3.5 week excursion the next day. Before install I hot wired cam temporarily inside the trailer and took a ride down the street in the truck to see how far I could go before I lost signal. It was at least 1-2 city blocks. Wow. Installed and worked perfectly cruising at 70-80mph. Refresh rate changes from nearly real-time to a slightly jumpy 15 frames a second. A few times screen would go black but then come back on, on the 3000 mi trip but - really - it worked fantastic especially w the HD quality. I highly recommend.
